The evidence clearly indicates that this theropod had lung and respiratory mechanics similar to that of a crocodile—not a bird. There was evidence of a diaphragm-like muscle separating the lung from the liver, much as you see in modern crocodiles. These observations suggest that this theropod was similar to an ectothermic reptile, not an endothermic bird. Did feathered dinosaurs exist?
Were dinosaurs warm blooded or cold blooded: Before beginning the argument we have to understand the term endothermy (homeotherms) and ectothermy (poikilotherms) : Endotherms: (endo, “inside”) , animals exhibit endothermy ,when they warm their tissues by the production of metabolic heat. Homeothermy : animals that thermoregulate by physiological means (rather than just by behaviour) Were dinosaurs warm or cold blooded ? Ectotherms : (ecto , “outside”) , animals exhibit ectothermy when thermal conditions outside the bodies of these animals determine their body temperature. Poikilothermy : body temperature of the animal is determined by equilibration with the thermal conditions of the environment and varies as environmental conditions vary.
Chapter six welcomes us into the skeletal system by presenting functions,types,structure, and development of bones. We are also presented the ideas of fractures and even the spine- curling snap of a broken bone which means a band aid simply won 't do! For example, Hematoma formation , Fibrocartilaginous callus, Bony callus ,and Remolding must occur to heal ,aka 3-10 weeks in a signature infested cast ,and if the break eventuated* on your arm, a complementary farmer 's tan. The Axial Skeleton makes an appearance by explaining itself as lying in the middle of the body and consisting of the skull, hyoid bone, vertebral column, thoracic cage, and middle ear bones. The complexity, physiology and delicate fashions of each member of this group is expressed.
In the passage, the author claims that the Edmontosaurus migrated south in order to survive. However, the lecture refutes the view in the reading and argues that the arguments are not convincing. First of all, the passage establishes the view that Edmontosaurus diet drove them southward because there would have been no plants alive in the North Slope. By contrast, the professor in the lecture contends that Edmontosaur does not need to migrate to South to get food. Edmontosaur can get good quality of plants since it was 24 hours of sunshine during summer.
The discovery of this mammal was proof that mammals had lived alongside the dinosaurs. It gave scientist a small glimpse into ancient mammal species. Chapter 6– Questions
The reading claims that, Edmontosaurus migrated every Winter and Provide some Reasons to Support the hypothesis. HOWEVER, the Lecture disagreed with the statement and LOGICALLY refutes each of the Reasons. Firstly, the Lecturer Claims That, Edmontosaurus did not migrate to Find Food. She said that, summers were warmer than today, and the sun shines 24 hours a day.
Title Researchers and scientists have constructed extensive research on dinosaur’s extinction. Speculation instead of real evidence seems common in most theories about the dinosaurs’ extinction. However, Jay Gould’s essay “Sex, Drugs, and the Extinction of Dinosaurs” is the complete opposite of speculation over evidence. Rather, Gould uses the mix of persuasive techniques, such as rhetorical questions, logos, along with profound evidence to not only disapprove of other theories but convince readers of his place on the dinosaur’s extinction.
As my team and I discovered a new fossil in our excavation project, the unknown site yielded the skull of a mysterious specimen. Our goal as reputable anthropologist was to analyze the specimen to the best of our ability so our team can provide the most probable and reliable taxonomic identification. In order for us to effectively interpret the results our experiment yielded, we needed to review our knowledge in human evolution. The field that uncovers the mystery of the evolution of humans is paleoanthropology, the study of human evolution through the fossil record.
Apparently the scientists have never seen Jurassic Park. It’s a clear reason of why you don’t try and bring extinct animals back to life. They’re dead for a reason. Anyways though, they just so happened to make the most dangerous dinosaurs first. They ended up growing faster than expected and were fully grown in 2 months.
The Earth's climate went through several major changes throughout the Tertiary period that led to the flourishing of primate species and the extinction of other primate species. The plesiadaptiforms, which are not considered real primates because of the lack of key primate features, went extinct at the end of the Paleocene epoch. At the beginning of the Eocene epoch came the euprimates, considered the first real primates, whose features made them well-adapted to arboreal life. Euprimates had convergent eye orbits, opposable digits, nails, and larger brains than plesiadaptiforms. This coincides with a period of global warming which made for a more tropical and forested habitat.
Endless theories and hypothesis’ surround the disappearance of the dinosaur species. Comets, asteroids, disease, and volcanic eruptions are just some of the presumed causes of their extinction. Which one is to believe? In “Sex, Drugs, Disaster, and the Extinction of Dinosaurs,” Stephen Jay Gould presents three proposals for their extinction: Sex, Drugs, and Disasters. Gould explains the three theories on the extinction of dinosaurs by giving a biologic and scientific reason for each, with the purpose of showing that scientific discoveries come from testable theories.
Ray Bradbury used figurative language to describe the Tyrannosaurus Rex in “A Sound of Thunder. ’’ Ray Bradbury compared the legs to pistons, this means that the Tyrannosaurus Rex has strong legs. He compared it’s eyes to ostrich eggs, this means that the dinosaur has big eyes. He also compared muscles to thick ropes, this means that the dino has big thighs.
Reptile scales act as a protective layer to help prevent water loss from their bodies. Mammals are warm-blooded animals and reptiles are cold-blooded animals. Mammals are endothermic which means they can produce and control their body heat internally. Reptiles are ectothermic, they use their resources such as the sun to get
BIOLOGY RESEARCH ESSAY There is great speculation around evolution. As we are continually in the process of discovering the history of human beings, there are many questions surrounding this topic. One very interesting question is why ancient ancestors of homo-sapiens evolved to walk upright like we do today. An apes’ DNA is astonishingly similar to that of a humans, (97% the same) and yet, our bones’ shapes and structure are very different.
Wildlife Conservation is often seen as a bad thing, but if you look at it from my perspective, then it is actually a good thing. People think of it as holding wild animals captive, but we are actually protecting them from poachers. The purpose of Wildlife Conservation is to protect the animals in danger, which I am in agreement 110%. Other people argue that we shouldn’t have conservations, but they don’t know the harm that can happen to unprotected animals.
